CASTER FOR TRUNKS.

EPECIPICATION forming part of Letters Patent No, 335,557, dated February9, 1886,

(No model.)

To all whom it may concern:

Be it known that I, PAUL C. Bmnsaoa, a citizen of the United States,residing at Milwaukee, in the county of Milwaukee and State ofWisconsin, have invented certain new and useful Improvements in Castersfor Trunks; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to letters orfigures of ref erence marked thereon, which form a part of thisspecification.

My invention relates to improvements in trunk-casters.

The construction of my improvements is explained by reference to theaccompanying drawings, in which- I 'Figure 1 represents a verticalsection of the retaining-bracket attached to the corner of a trunk,showing a side view of the caster-roller and retainingshank. Fig. 2 is atop view of the same device removed from the trunk. Fig. 3 represents afront view attached to a trunk. Fig. 4 represents the caster-roll andshank part in section removed from the retaining-bracket.

Like parts are represented by the same reference-letters throughout theseveral views.

A represents the retaining-bracket, which consists of the horizontalbottom plate, B, adapted to extend beneath and be secured to the bottomof the trunk by nails a, and the vertical corner-plates O 0, adapted tobe secured to the sides and ends of the trunk by nails 1) I), and theshank-retaining bilge D, adapted to serve the twofold purpose, first, ofa bumper, and, second, of a retaining-socket, permitting the shank toextend vertically therein and have a rotary movement alongside the sideof the trunk, all cast in a single piece.

E is the shank, which is provided with a socket or recess, F, and aconical-shaped head, G, said socket being adapted to receive and retainthe roller H, and the rolls of said socket being adapted to serve alsoas a shield to protect said roller horizontally on all sides fromcontact with other objects, and said head G being adapted to retain saidshank in position in said bracket A.

H is the roller, which is provided with trunnions d d.

I is a metallic block, which is cast in shape to conform to the cavitywithin the bracket A and to nicely fit the exposed side of the shank E.

In making my casters it is common to first cast the rollers H with thetrunnions (Z (Z, and to then coat the surfaces with finesand, which iscaused to adhere thereto by a coat of oil or like substance. The rollerthus coated is then placed in a mold, and the molten metal form ing theshank is cast around it. Upon cooling, the coating of sand is readilyremoved and the roller is free to turn in its bearings. The shank-androller being thus formed, the shank is in like manner coated with oiland sand, when it is placed in a mold, and the molten metal forming thebracket is cast around it. By this process nice closely-fitting jointsare formed between the roller and shank and the shank and bracket, whichare not only more perfect than could be made by forging, but are muchcheaper and neater in appearance. In case, however, it is desirous tohave the shank E removably attached to the bracket, the block I may inlike manner be cast separate within the bracket A, and partially aroundthe upper end of the shank, by first preparing the bracket and shank, asmentioned, by a coat of oil and sand, and then allowing the molten metalof which the block is composed to form within the bracket around theshank. This being done, the block I may be readily removed from theshank and the shank and roller removed from the bracket. \Vhen the shankand block are thus detachably made, they are held together, as shown inFig. 1, by contact of the block with the trunk, and the shank can onlybe removed by first detaching the bracket from the trunk. This done, theblock I is free to drop out of the bracket, when the opening through theside of the bracket permits the shank to be withdrawn therefrom.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination of the bracket A, having retainingplatcs B and O G,shank E, having head G, roller H, and the shank-retaining block I,substantially as and for the purpose In testimony whereof I affix mysignature in specified. presence of two Witnesses.

2. In roller-casters the shank E having the walls of itsroller-retaining recess extend over PA UL BIERSAOH' 5 the outer face andin front of the caster-roller, WVitnesses:
